Active Movement Chair with Lockable Wobble and Tilt Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chairs for work environments are inadequate for facilitating stretching and active physical movement, leading to sedentary behavior-related health issues such as back pain, muscle tightening, and reduced spinal flexibility, as they lack sufficient structural support and movement options for users.
Innovation Solution
The development of a chair with a seat support assembly that allows for height adjustment, rotation, and tilting in multiple directions, including side-to-side and front-to-back, along with an extension arm assembly for stretching, which includes handles and leg/foot supports to enable various active movements and stretches while seated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional chairs are used for work environments, then basic seating function is provided, but they fail to facilitate stretching and active physical movement
Solution Approach 1:
The chair incorporates a wobble assembly that allows the seat to dynamically tilt side-to-side and a tilt assembly that enables front-to-back tilting motion. These dynamic mechanisms transform the static chair into an active movement facilitator, allowing users to perform stretching exercises while seated without requiring complex external equipment
Solution Approach 2:
The chair integrates multiple functions into a single device: basic seating, height adjustment, rotation, side-to-side tilting for stretching, and front-to-back tilting for active movement. This multi-functionality eliminates the need for separate stretching equipment while maintaining a manageable structural complexity
2Adaptability or versatility
If chairs allow for movement while seated, then stretching capability is improved, but stability and support are reduced
Solution Approach 1:
The chair divides the tilting functions into separate assemblies: a wobble assembly for side-to-side motion and a tilt assembly for front-to-back motion. Each assembly can be independently controlled and locked, allowing users to stabilize the seat during periods requiring static support while enabling movement during stretching exercises
Solution Approach 2:
The lock assemblies enable users to self-regulate the stability of the chair based on their immediate needs. Users can engage the locks to stabilize the seat during typing or reading, and disengage them to enable stretching movements, providing on-demand stability control without requiring external assistance

AI summary
A chair may include a base defining a vertical axis of the chair, a seat configured to support a user thereon, and a seat support assembly disposed between the base and the seat in the direction of the vertical axis. The seat support assembly may include a height adjustment assembly configured to allow the seat to translate along the vertical axis, and a wobble assembly configured to allow the seat to tilt relative to the vertical axis in a side-to-side direction. The wobble assembly may include a wobble lock having a locked configuration, in which the wobble lock inhibits tilting of the seat relative to the vertical axis in the side-to-side direction, and an unlocked configuration, in which the wobble lock allows tilting of the seat relative to the vertical axis in the side-to-side direction.
